In regards to the ultimate path of University of Delaware associate professor Andreas Muenchow said the ice island will travel south and west to Nares Strait, and:

In Nares Strait, the ice island will encounter real islands that are all much smaller in size. The newly born ice-island may become land-fast, block the channel, or it may break into smaller pieces as it is propelled south by the prevailing ocean currents. From there, it will likely follow along the coasts of Baffin Island and Labrador, to reach the Atlantic within the next two years.

You hear about these ice calving events ... now, ships have to dodge icebergs all the time, but has there ever been a case where a massive block of ice, something on the order of "four times the size of Manhattan" has floated into shipping lanes?

"half as thick as the Empire State building [is tall]"

I was trying to figure out why someone would compare something to how thick the ESB was. Then I was like, there's no way the ESB is two football fields along its shortest dimension.

Yes. Back in the mid 90s I used to work for a major container shipping company, and I remember what I like to call an "OMG" event where one of our ships was going to be delayed by two days on a transatlantic route (Rotterdam-Halifax, if I remember correctly) due to an "ice event" in the North Atlantic. I got a call at 4AM from our regional GM telling me to get in the office right away as they needed to contact every customer with cargo on that ship, and they needed me to be on site to handle any IT issues if they cropped up.posted by deadmessenger at 1:48 PM on August 10, 2010 [3 favorites]

I wonder who coined the usage of "calving" to denote chunks of ice melting of a glacier. It makes something that seems like it should be a horrifyingly screeching canary in the coal mine into a cute, motherly ball of "aww..."posted by Blazecock Pileon at 2:03 PM on August 10, 2010 [1 favorite]

Pity this iceberg won't block the lanes of every highway on the planet. Just some distant, unseen shipping lane that won't inconvenience anyone but a few ships bring stuff that could be made locally from distant, low-cost centers of production.

I challenge everyone in this thread who will say something about Global Warming to park their car for a week a month or a year and find a carbon-free way of getting around. "Inadvertent climate modification" beings at home. Don't wait for the government, or the other guy to do something about it. Walk the talk or shut the hell up.

For all of my car-free friends with whom I share the bike lanes, let us mock the hypocrites.

NASA has an interesting write-up on the term

Hey, thanks for that. This sort of clears up the confusion between "global warming" and "climate change". At least in science papers, "global warming" means surface temperature changes while "climate change" means every other change (more storms, etc..). So when it's hot outside we say "global warming". When it's storming or drought we say "climate change".posted by stbalbach at 3:54 PM on August 10, 2010

Sorry, but I call bullshit. A billion hipsters riding fixies holding hands singing kumbaya won't stop the rest of the global population from destroying the planet. Either we get top-down regulation and market-based solutions which, via full international cooperation, succeed at capping global atmospheric carbon dioxide at 350ppm (50ppm below current levels) or you are totally screwed, regardless of how often you ride your bike. And by the way, agricultural and industrial sources of CO2 emissions dwarf personal vehicle contributions. Given your level of self-righteousness, I hope you're a vegetarian.posted by mek at 4:00 PM on August 10, 2010 [4 favorites]

Calving is a normal part of the glacial life cycle; as snowpack is added way up top and the compressed ice flows downhill towards the sea, the part that meets the ocean is naturally going to melt into it. This normally takes place at a rate that comes close to the rate at which new ice is being pushed toward the water, so the edge of the glacier stays in about the same place. The real trouble here, the truly terifying thing, is that these cute little calves are PREEMIES!posted by contraption at 4:01 PM on August 10, 2010

"Inadvertent climate modification" beings at home.

Begins at home, but only governance will finish it. Most people lack the knowledge and ability to make rational choices in this matter due to the vested interests pushing the other way. When you frame the issues of action like that, you are pitting one individual against the mighty, legion, behemoths of carbon-producing industry, with trillions of dollars, centuries of labour-time, sophisticated PR and lobbying skills and so much raw power it looks like thaumaturgy.

One individual against these interests in like an umbrella against a tsunami. Mek is right; political action is the most powerful thing you can do for climate change right now. This doesn't obviate personal choices but individual action is no substitute for political, collective action; they are two completely different things, and we need the latter not the former to save our planet and our species from a sad fate.

Judging people you've never met or know nothing about is less helpful. Your self-satisfaction is just another source of hot air.posted by smoke at 5:42 PM on August 10, 2010 [6 favorites]

The fact of the matter is, at least in the United States, that a lot of people have no choice. Jobs are scarce. Suburban sprawl has placed many people far from the city centers where they work. Public transportation is nil in many places, and still uses carbon based fuels. What do you suggest? People ride their bikes 60 miles to and from work in an urban center they couldn't afford to live in anyway. Vast amounts of wealth have become concentrated in the hands of a few, a few who actively fight against any real political action on climate change. It's just unfair to characterize people who don't "walk the talk" as hypocrites. I don't drive. I hate cars, but I never throw it in other people's faces because I realize that individual choices are too often beholden to the choices we have made as a collective throughout many decades prior to my existence. I agree with those who say political action is the way to go. It has to be. Also, as seen stated by a C-SPAN guest, "I agree with what I said."posted by IvoShandor at 3:55 AM on August 11, 2010 [3 favorites]

nice, but I prefer a Growler

And then things transition into highly technical terms like "small" and "very large."

Late to the game here, but the glacier is in northwest Greenland (the side that faces Baffin Island). Greenland is a fascinating land; read Gretel Ehrlich's dreamlike This Cold Heaven for an impressionistic look at the place.posted by Mister_A at 7:02 PM on August 11, 2010
